3 Terms and Definitions
The following terms and definitions apply to this document.
3.1
Personnel Engaged in Blasting Operations
Personnel who, after professional training and passing the assessment, obtain the corresponding qualifications and directly engage in seismic exploration blasting operations, including blasting engineering technicians, blasters (including packers, loaders), safety officers, and custodians.
3.2
Personnel Involved in Explosions
Personnel engaged in activities related to seismic exploration explosions.
Note: In addition to personnel engaged in blasting operations (3.1), this also includes blasting team leaders, warehouse security personnel, escorts, wire cleaners in contact with explosive materials, and drivers of explosive vehicles.
3.3
Minimum Burden
The minimum vertical distance from the center of the explosive charge to the free surface.
Note: In the case of a horizontal free surface, it is the distance from the center of the explosive charge to the ground surface.
3.4
Explosive Articles
Various types of explosives, seismic sources, detonators, detonating cords, etc., used in seismic exploration blasting operations, which have been approved by the state and meet safety standards.
3.5
Dynamite Bundle
An explosive charge column or explosive charge installed with a detonator.
3.6
Shot Wire
The wire connecting the detonator lead wire to the explosion machine.
3.7
Explosion Station
The position where the explosion machine and the blaster are located during blasting.
3.8
Pattern of Initiation
The method of initiating the explosion of industrial explosives using initiation devices.
3.9
Firing Circuit
A system that transmits initiation information and energy to multiple initiation explosive charges.
3.10
Misfire; Unexploded Charge
A phenomenon where the explosive charge fails to detonate as designed due to various reasons, resulting in partial or complete failure of the explosive charge to explode.
3.11
Sympathetic Detonation; Gap Initiation; Detonation by Influence
A phenomenon where another explosive (secondary explosive) explodes due to the action of shock waves when an explosive (primary explosive) explodes.
3.12
Destroy by Melting or Burning
A process of treating explosive materials (3.4) by methods such as blasting, burning, dissolving, and chemical decomposition to eliminate their explosive hazards.
3.13
Clearing Line
The process of handling duds (3.10) and other residual materials, including cleaning, disposal, and verification.
3.14
Emergency Response Plan
A pre - prepared work plan for emergency preparation to minimize damage from potential accidents.
4 General Requirements
4.1 Seismic exploration units engaged in explosive operations should have a “Blasting Operation Unit License” issued by the public security organs.
4.2 The main person in charge of the explosive unit is the first person responsible for the safety management of civil explosives in the unit, and is fully responsible for the safety management of civil explosives, personnel involved in explosive operations, and all links of explosive operations in the unit.
4.3 Seismic exploration units that carry out seismic exploration blasting operations across administrative regions at the county level or above should report relevant materials of the seismic exploration blasting project to the county - level (city - level) people's government and public security organs in the blasting operation area in advance, and handle relevant filing procedures.
4.4 In the links of purchasing, acceptance, storage, transportation, use, destruction, and clearing of explosive materials, the explosive unit should establish a safety education, management, post responsibility, and supervision mechanism, formulate safety operating procedures and accident emergency response plans, and effectively control the entire process of seismic exploration explosive operations.
4.5 Smoking, open flames, and carrying non - explosion - proof electronic devices and other electrical equipment should not be allowed in explosive areas. Seismic exploration operation sites should maintain a safe distance from electromagnetic and radio frequency induction facilities.
4.6 Personnel involved in explosive operations should hold valid certificates when performing various operations related to explosive materials, and should correctly equip and use safety helmets, protective goggles, protective clothing, and safety shoes according to GB 39800.1. Drinking is not allowed before and during work.
4.7 Personnel engaged in blasting operations have the right to refuse to execute orders and commands that violate this document, and to eliminate violations.
4.8 Construction should not be carried out by personnel involved in explosive operations under conditions where explosive safety operations are not available.
